BZ#2035124 introduced kernel change that is now causing failed build of audit:

1. rpmbuild --define '_topdir /tmp/tmp.QnGog2P0nh' -bc /tmp/tmp.QnGog2P0nh/SPECS/audit.spec

Version-Release number of selected component (if applicable):

kernel-5.14.0-96.el9
audit-3.0.7-102.el9
gcc-11.3.1-2.el9

How reproducible:

100%

Steps to Reproduce:

1. Download audit source rpm, install it and all its build dependencies.
2. Build the rpm.

Actual results:

See above.

Expected results:

Package can be built.

Additional info:

It is very likely that the same issue will affect RHEL-8.7 because of BZ#2035123.
